The Winnebago Pool is a collective name for a group of interconnected lakes in eastern Wisconsin.
[1] The terminal point of this watershed is Lake Winnebago itself, which has a surface elevation of 746 feet.
After the waters reach Lake Winnebago, they exit through the Lower Fox River and over the next 39 miles, the river drops over 150 feet to reach the lower water level of Green Bay.
The lakes of the Winnebago pool combine to encompass over 166,000 acres (672 km2) and account for nearly 17% of the total surface water area in Wisconsin (not counting the Great Lakes).
The Butte des Morts region is part of the Winnebago Pool.
